Inventor: KUMAGAI MITSUAKI
IPC: H02K5/10
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To provide a drop-proof coupling structure of a cover concerning the drop-proof structure of a handy terminal and capable of particularly preventing the cover from drips. SOLUTION: The tip end of the outer edge of a cover presses a U-shaped groove provided on the upper part of an elastic body of elastomer or the like double molded along the tip of the outer edge of a housing. For example, it presses three positions of both shoulder parts 5a, 5b and bottom part 5c of the groove 6 to deform the elastic body. As a result, even if the pointed tip of the outer edge of the cover does not contact the bottom part 5a of the groove 6, both shoulder parts 5a, 5b of the groove 6 are pressed and deformed, so that such position is blocked from the intrusion of water and a handy terminal can be surely prevented from drips.

Title: Continuous dephosphorizing and desulfurizing method for molten steel
Inventor: ONOYAMA SHUHEI
IPC: C21C7/064
Filed: 1988-09-29
Abstract: PURPOSE:To allow the continuous execution of dephosphorization and desulfurization without removing slag and without causing rephosphorization by blowing a dephosphorizing agent to a molten steel to dephosphorize the molten steel, then blowing a slag separating agent thereto to separate the molten steel and the dephosphorizing slag and blowing a desulfurizing agent to the molten steel. CONSTITUTION:The dephosphorizing agent is blown from a powder blowing tuyere 3 in a degassing chamber 1 into the molten steel in an undeoxidized state to dephosphorize the molten steel. The slag separating agent 10 is then blown into the molten steel 4 in the degassing chamber 1 and the molten steel 4 is moved into a ladle 5 where the slag separating agent 10 is positioned to the lower layer of the dephosphorizing slag 9 to separate the dephosphorizing slag layer 9 and the molten steel 4. Further, the molten steel is deoxidized by Al, Si, etc., and thereafter, the desulfurizing agent is blown from the tuyere 3 into the molten steel 4. The desulfurizing agent is positioned as desulfurizing slag 11 to the lower layer of the slag separating agent 10 in the ladle 5 by the movement of the molten steel 4. The dephosphorization and desulfurization are executed continuously in this way without removing slag, by which the productivity of the high-grade steel and the reduction of the heat loss are attained.

Title: Speaker device
Inventor: FUJIHIRA MASAO
IPC: H04R7/20
Filed: 1989-09-19
Abstract: PURPOSE:To reduce a low audio resonance frequency as evading the antiresonance of an edge member by forming a thin groove in a circumferential direction at the curvature part of the edge member supporting the periphery of a cone shape diaphragm. CONSTITUTION:Plural V-thin grooves 19 are formed in the periphery of the apex of the curvature part of a round shape free edge 17G. The width (w) and the depth (d) of the thin groove 19 are set, for example, as follows: w=0.3mm and d=0.4mm. By forming such thin groove 19, the creeping length in the radius direction of the edge 17G can be extended. In other words, effective width can be extended, and stiffness can be reduced. Also, as for sound pressure characteristic, no valley in a middle sound area is generated. Furthermore, since no effective radius of the diaphragm 11 is reduced, no reduction of an output sound pressure level occurs.

Filed: 1992-09-11
Abstract: PURPOSE:To provide a single-element type reception circuit using a light emitting element as a photodetector which can reduce a dark current of the light emitting element by lowering a backward bias voltage to be applied on the light emitting element. CONSTITUTION:In a reception circuit connecting in series a light emitting element 1 and a preamplifier 4 so that a backward bias is impressed thereto, a diode 2 is provided between the light emitting element 1 and the preamplifier 4.

Sensors 44-47 included in an arithmetic section 39 of a circuit section 37 measure the conditions of air flowing to and from the room. The measured values are processed by a microcomputer 43 against the values set by the arithmetic section 39. The processed results are inputted into a display section 40 as an output signal, so that the room temperature, humidity, outside air temperature, and time are displayed directly. The contamination of air, dew condensation, and weather are displayed on a panel 23 as warning display. The suction/exhaust blower 15 is operated automatically in accordance with the processing results. When humidification value is set on the display section 40, control is carried out from a humidifier 67 connected to an external equipment connecting switch 60.

Abstract: PURPOSE:To adjust the stylus force of a probe stylus whose projection length from a fixed frame is short by providing reinforcement parts which are set larger in sectional area than the probe stylus whose projection length is short to the intermediate parts of probe styli whose projection length from the fixed frame are long. CONSTITUTION:The probe card is equipped with the probe styli 4, 6a, and 6b whose projection lengths L1-L3 from the fixed frame 8 are different, and the probe styli 6a and 6b whose projection lengths L2 and L3 from the fixed frame 8 are long have the reinforcement parts (large-diameter parts 16a and 16b) which are set larger in sectional area than the probe stylus 4 whose projection length is short at their intermediate parts.

Abstract: PURPOSE:To record high-definition image by allowing a selective means to set the recording mode so that the length of the mirror side of a minimum modulation area formed on a recorded medium with the area modulation is to be a specific length. CONSTITUTION:A signal A(A1, A2...) is an image signal outputted from a D/A converter 5, and a signal B is a triangle wave from a chipper circuit 8, and the signals A, B are synchronized with a video clock signal. Moreover, a signal A(C1, C2...) is a signal resulting from the signals A, B compared and synthesized by a comparator 6, that is, a signal object to pulse width modulation. In the case of a relation of A>B, the output of the comparator 6 is set and in the case of a relation of A<=B, the output of the comparator 6 is cleared. Then in the case of forming an intermediate tone image by an area modulation means such as a pulse width modulation method, its minimum modulation area is selected to be a multiple pf 0.7-4 of a toner average particle diameter. Thus, an excellent intermediate tone image with gradation even at a highlight part is obtained by compensating the incomplete development area of a picture recorder.
